These ovens were made of stone, clay and brick. They looked like a borie and were used to make cade oil.
These ovens have a special shape. The heating chamber is heated to a temperature of 250 ° C. The fire surrounds the jar everywhere. During cooking, a viscous, brown substance with reddish relief flows in the jar deposited at the bottom of the oven: cade oil.
Especially present south of Sainte-Baume, the use of these ovens tends to disappear between 1940 and 1950. There was a time when the cade oil was bought by companies in cosmetics and pharmacy.
